Your main window is a classroom. Main and those,
I'm sorry that you've pumped into it. Ui_Start♪The objects of this main window are as follows:self.lineEdit1 ... например, self.lineEdit1.text()
self.textEdit ... например, self.textEdit.setHtml("<b>Привет Мир</b>")
self.pushButton_2 ... например, self.pushButton_2.clicked.connect(self.onClicked)
self.pushButton ... например, self.pushButton.clicked.connect(self.uch)
On the button self.pushButton_2 You create another window.
And it will be an object. self.inst♪
Attributes to this facility are as follows:self.inst.textEdit ...
self.inst.text_inctru ...
On the button self.pushButton You create another window.
And it will be an object. self.uch♪
Attributes to this facility are as follows:self.uch.lineEdit ...
self.uch.pushButton ...
self.uch.pushButton_2 ...
self.uch.label ...
These other windows will be ОКНАМИ ♪ 'cause he sees
The one who doesn't have a parent will be a window.
To show these other KONAs you must fulfil
self.inst.show() or self.uch.show() respectively.from PyQt5 import QtCore, QtGui, QtWidgets
